FREDERICK BRONNER, OF PORTLAND. OREGON, ASSIGNOR TO IRWIN-HUDSON CO., OF PORTLAND, OREGON.

I'NKING PAD.

Application led December 2, 1921.

To all whom t may concern.'

Be it known that I, FREDERICK H. BRON- NER, a citizen of the United States, and a resident of the city of Portland, county of Multnomah, and State of Oregon, have invented a certain new and useful Improvement in Inking Pads, of which the following is a specification.

The object of my invention is to provide an improved self-feeding inking pad for rubber stamps and the like, and particularly to improve the device secured to me by Letters Patent ofV the United States #1,321,785 issued November 11, 1919.

It was found that the gelatinous base provided in said device spread and did not stand up under continuous use, and besides the device was not so 'constructed that the worn parts thereof could be readily removed and replaced.

In my present invention I have overcome these defects by encompassing the gelatinous base by a wall of material of lesser resiliency and encompassing such wall by 25 a band-like metal shell.

Furthermore, my improved device is so contrived as to insure the spreading ofthe ink throughout the disk of absorbent material and prevent that portion of such disk lying directly over the resevoir from becoming saturated with ink. Furthermore, I encompass the circumference of the absorbent disk with a wall of non-absorbent material preferably constituting an integral part of the body of the inking pad, so that the ink will not ooze out over the circumference surface of the pad and thus soil the fingers of the user.

Furthermore, I so arrange the parts of my improved inking pad, that the bottom or gripping surface of the gelatinous pad will extend below` the bottom edge Aof said wall of lesser resiliency, in that way leaving the bottom portion of the vrgelatinous pad unrestrained so that it may exert a firm grip on the supporting surface without any danger of injuring the latter surface. i

The foregoing and incidental features of my invention are hereinafter fully described and illustrated in the accompanying drawings, in which Fig. 1 is a plan view of my device with L the cover removed, and parts broken away;

serial No. 511x404.

Fig. 2 is a side elevation of the same showing cover in section;

Fig. 3 is a cross sectional view taken on the line 3--8 of Fig. 1;

Fig. l is a cross sectional view of the metal shell of my pad taken on the line c-; of Fig. 1;

Fig. 5 is a plan view of the skeleton bodyl of my pad;

Fig. 6 is a plan view of the perforated metal disk which prevents the absorbent layer from becoming sagged and also serves the purpose of vdistributing ink more evenly across the surface of the pad than hereto fore;'and

Fig. 7 is a sectionalized detail view of the cover and the metal shell of the base, and illustrates the loose tit of the cover on the top of my pad.

I have provided a skeleton rubber body c which gives a rigidity to the pad and forms the frame work for all of the parts.

The skeleton body consists of a web a having an integral pending flange-like wall a2, the latter being the portion encompassing the circumference of the gelatinous base e. Another flange-like wall a3 projects above the web a. The skeleton body is contained in band like metal shell c preferably made of aluminum. This shell issecured in place on the pendent wall a2 of the body by providing the latter with locking lugs Z) adapted to project through holesc provided in the shell c. The shell c extends to the top of the upper wall a3 of the skeleton body so as to sup port such upper wall, but does not extend quite to the bottom of the lower wall a2 of the skeleton body; and the bottom portion of the gelatinous base projects below the bottom edge of the skeleton body. In this way is assured sufficient stability to the base, at the same time leaving its supporting bottom face amply yielding to assure a firm grip'on the desk or other supporting surface, and further insuring that the latter will not be scratched or marred.

Within the upper wall a3 of the skeleton body a is placed a disk of absorbent material la. The center of the skeleton body is provided with an ink reservoir or chamberh consisting of an annular wall projecting downward from the center portion ofthe lower side of the web a; the link chamber 71,

is open at both ends, its lower end being closed by a plug g. rlhe upper face of the web a of the body is provided With distributing channels f radiating from the ink chamber g. In order to insure the better distribution of the ink, and prevent the central portion of the absorbent disk 7c from becoming saturated with the ink, a metal disk 7' of the construction shown in Fig. 6 is placed between the web of the body and the disk 7c. As more clearly shown in F ig. 6 the center of this metal disk y' is solid, and it has radially disposed perforations y" from points equi-distant from the center to the edge.

It is to be noted that the circumference of the skeleton body at the top is contracted, and the upper portion m of the shell inclines inward; in other words provides a sloping exterior surface on which the cover z' rests. Such construction gives the cover a loose fit, and renders it easy to remove.

The upper surface of the absorbent pad 7c is covered as usual with closely woven silk or similar fabric.

rPhe composition of which the base e is made may be the same as that described in my previous patent. The composition is heated and poured into the bottom cavity of the skeleton body with the latter inverted. To insure firm adhesion between the skeleton body and the gelatinous base, the web a of the former may be provided with holes rl into which the gelatinous mass will flow and thus form locking studs e on the upper part of the base. See Fig. 3.

The metallic shell is easily removable and thus affords a means whereby the pad can be recovered or the separate parts renewed without discarding` the entire pad. It also provides a means whereby the separate parts of the pad can be replaced as often as necessary with a minimum amount of cost and annoyance.
